TRUCK CONSTRUCTION.

Specification of Letters Patent.

-Patented Dee. 9, 1913.

To all whom t may concern:

15e it known that we, CLARENCE Il. How- Ann and HARRY M. Primera, citizens of the United States, residing at the eity of St. Louis, State of Missouri, have invented a certain new and useful lmprovement in Truck Construction, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it. :'i] ipei'tiiiiis to make and use the same, reference being had to the accompanying drawings, forming pari; of this specification, in whieh- Figure l is a iop plan view of the side portion of a truck of our improved con struction. vFig. 2 is a side elevational View of a truck with parts thereof in vertical section. Fig. 3 an enlarged detail section taken approximately on the line Sie?) of Fig. 2. Fig. l is an enlarged detail section taken approximately on the line 4--l of l `ig. Q. Fig. 5 is a side elevational view of a portion of a truck and showing a modified cons-truction of the wheel pie. y

Our invention relates generally to railway car truck construction, and more. specifically to a new and ii'nproved construction and arrangement ol the truck frame side rails lor wheel pieces and the truck equalizing members, and this application should be read in connection with an application on truck construction filed by us November 18th, 1912 Serial No. 732,099.

The principal object of our present invention is to produce a truck wherein the equalizing members are disposed and combined with parts ofl the truck frame so as. to in no wisc interfere with the free inspection and repair of.' the. brakes, brake heads' and other parts of the truck equipment within the truck frame.

Further objects of our invention are to materially increase the strength of the truck without increasing the weight thereof, to produce increased flexibility of the truck,to equalize the distribution of weight upon all of the: wheels of the truck, and to arrange and dispose the equalizing members wholly above the journal boxes of the truck and yet keep Well' within a limited space between the tops ot' the track rails and the top of the truck frame.

For the purpose of illustratiner our invention, we have shown it applied3 to a six- .wbeel truck, but it will be readily linderstood that the same arrangement can be employed on trucks having other wheel arprise a vertically disposed web 8, an outwardly projecting top flange 9, and an in-A wardly projecting bottoni flange 10. By such construction, the strength of the truck frame is materially increased and Ythe flanged wheel pieces are formed so as to accommodate the equalizing ,members forming a part of the truck construction.

il designates pedestals, the upper portions of which are 'formed substantially box shape in cross section and each. pedestal being provided with a pair of jaws 12 which extend downward on the sides of the journal box in the usual manner and the lower ends of these jaws are united by a tie strap 13. The upper box shaped portion oi" each pedestal occupies a position immediately against the vertical web S and beneath the top flange 9 and said pedestal being fixed to the wheel piece in any suitable manner, preferably by means of bolts 11a. It desired, an inwardly projecting flange 12a ma be formed integral wi-th each pedestal wliie flange extends beneath and is fixed to the inwardly projecting flange l() of the w'lieel piece.

Positioned beneath the outwardly projecting top flange of each wheel piece and between thel rertically disposed webs ll are rigid cqualizing members ll, the same bein fulcrunied at 15 upon thev flange 9. The en s of these rigid equalizing members 1l engage the ends of' half elliptic springs 1G, the same resting upon the journal boxes 3 and forming the flexible equalh/.ing members. The central portion of the bottom plate or wall of the box shaped upper portion of each pedestal is eut away so as to permit the central portion of each flexible equalizer t0 rest or bear upon the top of the correspondpairs of wheels is obtained.

ang journal box. 'At the extremities of' the wheel piece, the outer ends of thev springs creasing the flexibility of the truck, the riding movement of the car is made comparatively easy, and by locating the equalizing members against the sides of the wheel pieces and immediately below the top flanges .9thereof, the entire lower portion ofthe truck is practically unobstructed and free to inspection and repairs.

'-By constructing the wheel pieces substan- .tially Z-shape in cross section throughout their length, a very strong and rigid con- '.struction is provided, and the equalizing members arranged against the vertical webs of said wheel piece and beneath the top flange thereof are readiljv accessible for inspeetion and repair.

1 In Fig. 5, -we have shown a modified construction wherein a vertically disposed web or `plate 18 is formed integral with the top Aflange 9 immediately over and adjacent to the journal boxes which construction materially strengthens the wheel piece over the journal boxes and provides a vertically disposed wall to which the upper portion of the edestal may be fixed.

` 'fe are `aware that arrangements of the parts other than those herein shown and de- .scribed may be made without departing Q40.

from the spirit of our invention, and it is intended that the scope of our invention as set forth in the claims shall be construed to include all obvious changes and arrangements.

We claim:

1. rlhe combination with a car truck frame having wheel pieces lying wholljv above the journal boxes of the truck, whicn wheel vpieces are provided with outwardly presented top flanges, and a series of equalizing members arranged adjacent to the vertical Webs of the wheel pieces and between the journal boxes and the flanges thereof.

By thus ini Q. The combination with a car truck frame having flanged wheel pieces lying 'wholly above journal boxes of the truck, a series of flexible equalizing members mounted lon the journal boxes of the truck. and rigid equalizing members fulcrumed on the. langes of' thc wheel pieces and cooperating; with said flexible equalizing members.

Il. in a car truck, the 'combination 4with wheel carrying axles and journal boxes. of a truck frame'having wheel pieces lying wholly above the axles and journal boxes, which wheel pieces are provided with outwardly projecting flanges near their tops, equalizing bars positioned beneath said flanges andfulcrumed thereon. and equalizing 'springs supported by the journal noxes and engaging said equalizing bars.

4. In truck construction, the combination with wheel carrying axles and journal boxes, of a truck frame having Wheel pieces which are Z-shape in cross section, and a series of equalizing members positioned between the journal boxes and the top flanges f the wheel pieces.

In a truck construction, the combination with a series of wheel carrying axles and journal boxes, of a truck frame having wheel pieces which are Z-shape in cross section. and a series of alternateljv arranged flexible and rigid equalizing members arranged between the journal boxes and the top flanges of the wheel pieces for yieldingly supporting said truck frame.

t3. In a truck construction, the combination with a series of wheel carrying axles and journal boxes, of a truck frame having wheel pieces each comprising a vertically disposed web and a pair of horizontallydisposed flanges projecting in opposite directions. and a series of equalizing members arranged between the journal boxes and the upper llanges of the wheel pieces for yieldinglv supporting said truck frame.

Vln testimony whereof we hereunto aflix our signatures in the presence of two witnessesthis 19th day of November, 1912.
